13. OPERATION
13.1. MANUAL OPERATION
In MANUAL mode the appliance works without power supply. If there is electrical voltage, the appliance will still work, the display will stay
on, and all the automatic functions provided are excluded.
During MANUAL operation the COMB must remain blocked in an upright position ( Picture 8 at page 40 B ).
After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses
and deformations. You should always use the product with the door closed in order to avoid damages due to overheating (forge
effect). The inobservance of this rule makes the warranty expire.
For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for removing
the ashes, while during the operation and the rest, the door of the hearth must remain closed.
The appliances with constructive system 2 must be connected to their own flue. The operating with open door is allowed under supervision.
IMPORTANT: For safety reasons the door of the hearth can be opened only for the loading of the fuel. The hearth door must
always remain closed during operation or rest .
With the controls positioned on the front of the appliance it is possible to adjust the heat emission of the hearth. They have to be opened
according to the calorific need. The best combustion (with minimum emissions) is reached when, by loading the wood, most part of the air
for combustion flows through the secondary air register.
Never overload the appliance (see the hourly wood load in the table here below). Too much fuel and too much air for the combustion may
cause overheating and then damage the stove. You should always use the appliance with the door closed in order to avoid damages due
to overheating (forge effect). The inobservance of this rule makes the warranty expire .
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of 10 Pa (1,0 mm of column of
water) is the following one: see chapter TECHNICAL DESCRIPTION.
Besides the adjustment of the air for the combustion, the intensity of the combustion and consequently the thermal performance of the
device is influenced by the stack. A good draught of the stack requires a stricter adjustment of air for combustion, while a poor draught
requires a more precise adjustment of air for combustion.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that the
combustion is not complete (it is necessary a greater quantity of secondary air).
13.2. AUTOMATIC OPERATION
The AUTOMATIC operation is ONLY provided with the use of pressed wood briquettes .
The pressed wood briquettes must have a diameter of 60-70-80-90-100 mm, a maximum length of 340 mm, and must comply with the
features described by the existing standards in force.
Ensure the briquettes have been fed as described in the PRESSED WOOD BRIQUETTES FEEDING chapter and make sure the
COMB is released as described in the IGNITION chapter-Predisposition for the AUTOMATIC operation mode.
The ignition procedure is described in the previous IGNITION chapter. Proceed with the AUTOMATIC system ignition as described below:
a) Provide electrical voltage, put the master switch in position 1 ( Picture 7 at page 40 A ).
b) Press and hold button P1 Picture 7 at page 40 select AUTOMATIC function. By selecting AUTOMATIC mode, “AUTOMATIC feed stand-
by” will appear on the display.
From now on the appliance will self-feed until the pressed wood briquettes feeding in the tank is complete. Once feeding is complete
a BRIQUETTES UNLOADING ALARM appears on the display. Provide for feeding as described in the chapter PRESSED WOOD
BRIQUETTES FEEDING.
To stop the AUTOMATIC operation mode , press and hold button P1 and on the display “wood MANUAL wood” appears.
IMPORTANT: Fuel must NEVER be introduced manually in the furnace during AUTOMATIC operation. FUEL MUST NEVER BE
FED ABOVE THE COMB! Feeding the fuel above the comb will cause the glass door to break. Therefore, the replacement of
the glass is not covered by warranty. ( Picture 7 at page 40 ) .
SLEEP function : Press P2 – P3 simultaneously to activate the SLEEP feature if different from Off. Pressing and holding P1 excludes
SLEEP. During AUTOMATIC operation it is possible to set the SLEEP function from the USER MENU to establish the time after which
the stove blocks the briquettes automatic feeding and switches to the MANUAL operation mode.
13.3. OPERATION IN TRANSITION PERIODS
During transition periods when the external temperatures are higher, if there is a sudden increase of temperature it can happen that the
combustion gases inside the flue cannot be completely sucked up.
The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently and increase the air
for the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning (growing up of the flames) and the stabilization
of the draught. Then, check that all openings for the cleaning and the connections to the stack are air-tigh.
In case of doubt, do not operate the product.
14. SUMMER STOP
After cleaning the hearth, chimney and hood, totally eliminating the ash and other eventual residues, close all the doors of the hearth
and the relevant registers; in case you disconnect the appliance from the chimney you must close its openings in order to let work others
possible appliances connected to the same flue.
We suggest performing the cleaning operation of the flue at least once per year; verifying in the meantime the actual status of the rope
seals, which cannot ensure the good operation of the equipment if they are not in good condition and are not making a good seal! In this
case the seals must be replaced.
In presence of dampness in the room where the stove has been placed, we advise you to put absorbent salts into the hearth.
If you want to keep for long the aesthetic look of the cooker it is important to protect its internal walls in row cast iron with neutral Vaseline.
